Vodacom ********** Upgrade

I've been contacted by someone ***) representing Vodacom stating that I was eligible for an upgrade. After she read me my terms and conditions, I decided to cancel my contract completely, mostly because I live abroad and maybe use my Data Device once a year (Thus I'm really just wasting a lot of money).

She then told me that I can't cancel my Vodacom contract. That is weird, since my 24 month contract has expired and I don't want to renew - trust that is within my rights.

So I asked to please not renew anything, send me Reference Number for the call and I will contact Vodacom myself to sort it out. She said I will get a reference number directly after the call via SMS. I NEVER RECEIVED ANY REFERENCE.

I contact Vodacom's Cancellation Department 10 minutes later and they said that my account has been upgraded. HOW IS THIS POSSIBLE IF I HAVEN'T CONSENTED TO ANYTHING - WHY DO YOU HAVE RECORDINGS AND REFERENCE NUMBERS IS THE SYSTEM IS FAILING.

Unfortunately, as I'm calling from abroad the line dropped and we got disconnected. I've been trying for quite a while to reach Vodacom Cancellations again to stop this ********** ACTION, but is not getting through.

HOW IS THIS POSSIBLE IF I HAVEN'T CONSENTED TO ANYTHING - WHY DO YOU HAVE RECORDINGS AND REFERENCE NUMBERS IS THE SYSTEM IS FAILING.

I'm not sure who this person/company is who is calling on behalf of Vodacom, but I want my CONTRACT CANCEL WITH IMMEDIATE AFFECT!

Can someone from Vodacom Customer Service please take this matter seriously and get back to me - this is ********** and I want this matter resolved.

I would also like to know who was the agent that authorized the upgrade and feedback on how the matter is resolved from Vodacom's end.

Please contact me to verify my account details.

Thank you in advance.
